DISPLAY DEVICE WITH BINARY MODE AMOLED PIXEL PATTERN

摘要

An AMOLED display panel comprising a plurality of color elements in each pixel with each of the color elements comprising a discrete plurality of illuminating units associated with a plurality of transistors operating in a binary mode. The plurality of illuminating units have different sizes in accordance with 2n size, where n is the illuminating unit's number. n may also be the bit position of the bit line that controls the illuminating unit. The collective luminance of each color element can be digitally controlled by selectively activating a combination of the discrete illuminating units to their nominal luminance. The discrete plurality of illuminating units in each pixel may be directly controlled by RGB pixel data without the requirement for digital analog conversion.
